Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552236, here are decompositions:

7 + 31552229 = 31552236
29 + 31552207 = 31552236
43 + 31552193 = 31552236
97 + 31552139 = 31552236
109 + 31552127 = 31552236
167 + 31552069 = 31552236
179 + 31552057 = 31552236
239 + 31551997 = 31552236

Showing the first eight; more decompositions exist.
